Functional film
Thermoplastic Polyurethane Film
TPU(Thermoplastic Polyurethane) Film?
- It is widely used in various fields due to its fingerprint recognition (supports ultrasound), excellent adhesion (curved full cover), high-definition image quality (special UV hard coating), low price, lightweight material, and resistance to contamination
Necessity?
- Recently, the development of a TPU that can be attached to curved surfaces has become necessary due to changes in 3D structures and folding displays
Key Features
- 1. Ultrasonic fingerprint recognition
- Provides a perfect and soft touch unique to urethane material
- 2. Excellent adhesion
- Strong adhesion allows attachment to curved surfaces without defects
- 3. High-definition image quality
- Prevents glare (sparkling) through special UV hard coating treatment
- 4. Anti-fingerprint
- AF Coating on the film surface prevents external contamination such as fingerprints, oil, and cosmetics
